Isn't this too generous?

I tried it as my first Monster Hunter game because of a points-based activity. Um... I'm Hunter Rank 12 now, and right off the bat, they gave me Grade 10 weapons and Grade 8 armor. Because of that, I've been able to solo monsters like Rathalos and Brachydios pretty easily, like, seriously? I traded for a Grade 10 Switch Axe for now, but which weapon type is generally the strongest? I've tried them all, but I think the slow-attack, high-damage 'romance cannon' types like Great Sword, Long Sword, Switch Axe, and Gunlance suit me best lol While doing all this, I've already reached Hunter Rank 20, lol.
